FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques and apparatuses for video awaretransmission and multiple input multiple output (MIMO) layer processing.

BACKGROUND

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless network may include a number of base stations (BSs) that cansupport communication for a number of user equipment (UEs). A UE maycommunicate with a BS via the downlink and uplink. The downlink (orforward link) refers to the communication link from the BS to the UE,and the uplink (or reverse link) refers to the communication link fromthe UE to the BS. As will be described in more detail herein, a BS maybe referred to as a Node B, a gNB, an access point (AP), a radio head, atransmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or thelike.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. NR, which may also be referred to as5G, is a set of enhancements to the LTE mobile standard promulgated bythe 3GPP. NR is designed to better support mobile broadband Internetaccess by improving spectral efficiency, lowering costs, improvingservices, making use of new spectrum, and better integrating with otheropen standards using orthogonal frequency division multiplexing (OFDM)with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDMand/or SC-FDM (e.g., also known as discrete Fourier transform spreadOFDM (DFT-s-OFDM)) on the uplink (UL), as well as supportingbeamforming, multiple-input multiple-output (MIMO) antenna technology,and carrier aggregation. As the demand for mobile broadband accesscontinues to increase, further improvements in LTE, NR, and other radioaccess technologies remain useful.

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein, one skilled in the art should appreciate that thescope of the disclosure is intended to cover any aspect of thedisclosure disclosed herein, whether implemented independently of orcombined with any other aspect of the disclosure. For example, anapparatus may be implemented or a method may be practiced using anynumber of the aspects set forth herein.

It should be understood that any aspect ofthe disclosure disclosed herein may be embodied by one or more elementsof a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It should be noted that while aspects may be described herein usingterminology commonly associated with a 5G or New Radio (NR) radio accesstechnology (RAT), aspects of the present disclosure can be applied toother RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G(e.g., 6G).

FIG. 1 is a diagram illustrating an example of a wireless network 100,in accordance with the present disclosure. The wireless network 100 maybe or may include elements of a 5G (NR) network and/or an LTE network,among other examples. The wireless network 100 may include a number ofbase stations 110 (shown as BS 110 a, BS 110 b, BS 110 c, and BS 110 d)and other network entities. A base station (BS) is an entity thatcommunicates with user equipment (UEs) and may also be referred to as anNR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmitreceive point (TRP), or the like. Each BS may provide communicationcoverage for a particular geographic area. In 3GPP, the term “cell” canrefer to a coverage area of a BS and/or a BS subsystem serving thiscoverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). ABS for a macro cell may bereferred to as a macro BS. ABS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1, a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces, suchas a direct physical connection or a virtual network, using any suitabletransport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1, a relay BS 110 d may communicate with macro BS 110 a and a UE120 d in order to facilitate communication between BS 110 a and UE 120d. A relay BS may also be referred to as a relay station, a relay basestation, a relay, or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, such as macro BSs, pico BSs, femto BSs, relay BSs, orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, or the like. A UE may be a cellular phone(e.g., a smart phone), a personal digital assistant (PDA), a wirelessmodem, a wireless communication device, a handheld device, a laptopcomputer, a cordless phone, a wireless local loop (WLL) station, atablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook,a medical device or equipment, biometric sensors/devices, wearabledevices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, and/or location tags, that may communicate with a basestation, another device (e.g., remote device), or some other entity. Awireless node may provide, for example, connectivity for or to a network(e.g., a wide area network such as Internet or a cellular network) via awired or wireless communication link. Some UEs may be consideredInternet-of-Things (IoT) devices, and/or may be implemented as NB-IoT(narrowband internet of things) devices. Some UEs may be considered aCustomer Premises Equipment (CPE). UE 120 may be included inside ahousing that houses components of UE 120, such as processor componentsand/or memory components. In some aspects, the processor components andthe memory components may be coupled together. For example, theprocessor components (e.g., one or more processors) and the memorycomponents (e.g., a memory) may be operatively coupled, communicativelycoupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, or the like. A frequency may alsobe referred to as a carrier, a frequency channel, or the like. Eachfrequency may support a single RAT in a given geographic area in orderto avoid interference between wireless networks of different RATs. Insome cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol or avehicle-to-infrastructure (V2I) protocol), and/or a mesh network. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

Devices of wireless network 100 may communicate using theelectromagnetic spectrum, which may be subdivided based on frequency orwavelength into various classes, bands, channels, or the like. Forexample, devices of wireless network 100 may communicate using anoperating band having a first frequency range (FR1), which may span from410 MHz to 7.125 GHz, and/or may communicate using an operating bandhaving a second frequency range (FR2), which may span from 24.25 GHz to52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred toas mid-band frequencies. Although a portion of FR1 is greater than 6GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 isoften referred to as a “millimeter wave” band despite being differentfrom the extremely high frequency (EHF) band (30 GHz-300 GHz) which isidentified by the International Telecommunications Union (ITU) as a“millimeter wave” band. Thus, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like, if usedherein, may broadly represent frequencies less than 6 GHz, frequencieswithin FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz).Similarly, unless specifically stated otherwise, it should be understoodthat the term “millimeter wave” or the like, if used herein, may broadlyrepresent frequencies within the EHF band, frequencies within FR2,and/or mid-band frequencies (e.g., less than 24.25 GHz). It iscontemplated that the frequencies included in FR1 and FR2 may bemodified, and techniques described herein are applicable to thosemodified frequency ranges.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1.

FIG. 2 is a diagram illustrating an example 200 of a base station 110 incommunication with a UE 120 in a wireless network 100, in accordancewith the present disclosure. Base station 110 may be equipped with Tantennas 234 a through 234 t, and UE 120 may be equipped with R antennas252 a through 252 r, where in general T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI)) and control information (e.g.,CQI requests, grants, and/or upper layer signaling) and provide overheadsymbols and control symbols. Transmit processor 220 may also generatereference symbols for reference signals (e.g., a cell-specific referencesignal (CRS) or a demodulation reference signal (DMRS)) andsynchronization signals (e.g., a primary synchronization signal (PSS) ora secondary synchronization signal (SSS)). A transmit (TX)multiple-input multiple-output (MIMO) processor 230 may perform spatialprocessing (e.g., precoding) on the data symbols, the control symbols,the overhead symbols, and/or the reference symbols, if applicable, andmay provide T output symbol streams to T modulators (MODs) 232 a through232 t. Each modulator 232 may process a respective output symbol stream(e.g., for OFDM) to obtain an output sample stream. Each modulator 232may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM) to obtain received symbols. A MIMO detector 256 may obtainreceived symbols from all R demodulators 254 a through 254 r, performMIMO detection on the received symbols if applicable, and providedetected symbols. A receive processor 258 may process (e.g., demodulateand decode) the detected symbols, provide decoded data for UE 120 to adata sink 260, and provide decoded control information and systeminformation to a controller/processor 280. The term“controller/processor” may refer to one or more controllers, one or moreprocessors, or a combination thereof. A channel processor may determinea reference signal received power (RSRP) parameter, a received signalstrength indicator (RSSI) parameter, a reference signal received quality(RSRQ) parameter, and/or a channel quality indicator (CQI) parameter,among other examples. In some aspects, one or more components of UE 120may be included in a housing 284.

An antenna panel, an antennagroup, a set of antenna elements, and/or an antenna array may includeone or more antenna elements coupled to one or more transmission and/orreception components, such as one or more components of FIG. 2.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports that include RSRP, RSSI, RSRQ, and/or CQI) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In someaspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE120 may be included in a modem of the UE 120. In some aspects, the UE120 includes a transceiver. The transceiver may include any combinationof antenna(s) 252, modulators and/or demodulators 254, MIMO detector256, receive processor 258, transmit processor 264, and/or TX MIMOprocessor 266.

FIG. 3 is a block diagram conceptually illustrating an example of awireless communication network 300 in which a BS (e.g., BS 110) providesstreaming video to a UE (e.g., UE 120), in accordance with variousaspects of the present disclosure. As shown in FIG. 3, wirelesscommunication network 300 may include an Internet Protocol (IP)multimedia core network subsystem (IMS) core 305, a packet data networkgateway (PGW) 310, a serving gateway (SGW) 315, a BS 110 (e.g., whichmay include a communication device 320), and a UE 120. As further shownin FIG. 3, BS 110 and UE 120 may communicate via an access link (e.g., aUu interface).

PGW 310 includes one or more devices capable of providing connectivityfor UE 120 to external packet data networks (e.g., via IMS core 305).For example, PGW 310 may include one or more data processing and/ortraffic transfer devices, such as a gateway, a router, a modem, aswitch, a firewall, a network interface card (NIC), a hub, a bridge, aserver device, an optical add-drop multiplexer (OADM), or any other typeof device that processes and/or transfers traffic. In someimplementations, PGW 310 may aggregate traffic received from one or moreSGWs 315, and may send the aggregated traffic to IMS core 305.Additionally, or alternatively, as described in more detail herein, PGW310 may receive traffic from IMS core 305 and may send the traffic to UE120 via SGW 315 and BS 110. For example, PGW 310 may receive a videostream from IMS core 305 that is to be provided to BS 110 for processingand transmission to UE 120 UE 120.

SGW 315 includes one or more devices capable of routing packets. Forexample, SGW 315 may include one or more data processing and/or traffictransfer devices, such as a gateway, a router, a modem, a switch, afirewall, a NIC, a hub, a bridge, a server device, an OADM, or any othertype of device that processes and/or transfers traffic. In someimplementations, SGW 315 may aggregate traffic received from one or moreBSs 110 associated with the wireless communication network 300 and maysend the aggregated traffic to IMS core 305 (e.g., via PGW 310) and/orother network devices. SGW 315 may receive traffic from IMS core 305(e.g., via PGW 310) and/or other network devices and may send thereceived traffic to BS 110 for processing and transmission to UE 120.For example, SGW 315 may receive real-time transport protocol (RTP) dataand/or real time control transport protocol (RTCP) data with an RTPpayload format H.264 (e.g., RTP data conveying the streaming video viageneral packet radio service (GPRS) tunneling protocol (GTP)). In thiscase, SGW 315 may provide the RTP data and/or RTCP data (e.g., thestreaming video) to BS 110 via GTP and RTP and/or RTCP.

In some communications systems, such as Video Over 5G/NR (VoNR) or VideoOver LTE (ViLTE), a BS and a UE may communicate using full duplex voicewith either simplex or full duplex video streaming. The BS and UE mayenable a relatively high level of synchronization between the voice andvideo streaming (which may be referred to, collectively, as streamingcontent), thereby enabling video-calling, streaming entertainment,and/or the like. The BS may activate dedicated bearers for transport ofvideo and audio RTP traffic. The BS may assign different quality ofservice (QoS) levels for video (e.g., QoS class identifier (QCI) 2 forvideo) and audio (e.g., QCI 1 for audio), thereby providing somedifferentiation in reliability. For example, in this case, the BSprioritizes streaming audio, which may be delay and jitter sensitive,over streaming video, which may be less delay or jitter sensitive. Inother words, during a video-conference use case, a brief interruption toaudio from a speaker may be more disruptive to the video-conference thana brief interruption to video of the speaker.

However, at a medium access control (MAC) layer or physical (PHY) layer,the BS may perform procedures, such as scheduling, coding, modulation,multiplexing, orthogonal frequency division multiplexing (OFDM) symbolgeneration, and/or the like, agnostic of data that is being processed.In other words, the BS may process all data of a video stream withoutregard to what part of the video stream the data represents. As aresult, interruptions to data transmission may result in excessivelylarge effects to quality of experience (QoE) when the interruptionaffects a part of a video stream that has a large QoE effect.

Some aspects described herein provide video aware processing forstreaming video. For example, as described below, a communication device(e.g., a BS or a component of a BS) may classify portions of streamingvideo based at least in part on an effect of each portion on QoE for thestreaming video and may provide differential protection to portionsbased at least in part on the classification. In other words, thecommunication device may assign different portions of streaming video todifferent code blocks and/or transport blocks based at least in part onthe classification. For example, the communication device may generate afirst data stream for header data (e.g., RTP, user datagram protocol(UDP), IP header data) (a lack of which may have a first effect on QoE),a second data stream for transparent operation (a lack of which may havea second effect on QoE), a third data stream for a first QoSclassification (a lack of which may have a third effect on QoE), afourth data stream for a second QoS classification (a lack of which mayhave a fourth effect on QoE), and/or the like.

In this case, the communication device may provide differentialprotection to the different code blocks and/or transport blocksassociated with different data streams by mapping the different codeblocks and/or transport blocks (e.g., the data streams composed thereof)to different multiple input multiple output (MIMO) layers to providedifferential reliability. In some aspects, each MIMO layer may have adifferent signal to noise ratio (SNR) and the communication device mayassign different data streams to different MIMO layers based at least inpart on the different SNRs to achieve differential reliability. In thisway, the communication device ensures higher reliability for dataassociated with providing a high level of QoE relative tonon-video-aware processing, thereby increasing QoE of streaming video.In other words, the communication device may provide relatively higherprotection to code blocks and/or transport blocks conveying data fromdata streams with a higher effect on QoE and relatively lower protectionto code blocks and/or transport blocks conveying data from data streamswith a lower effect on QoE. In this way, the communication deviceensures that data with a greatest effect on QoE (e.g., a greatestlikelihood of interrupting consumption of the streaming video) is leastlikely to be dropped rather than all data having an approximately equalor randomly distributed likelihood of being dropped as may occur innon-video-aware processing. Although some aspects are described hereinin terms of streaming video, other types of streaming content arecontemplated.

Communication device 320 may include BS 110 or be a component of BS 110.For example, communication device 320 may be a video processingcomponent that includes one or more of controller/processor 240,transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234,and/or the like of BS 110. As shown in FIG. 3, BS 110 may decomposeand/or transcode received packets (e.g., packets received from SGW 315)to identify underlying aspects of the data, such as different aspects ofthe streaming video (e.g., different video aspects, different audioaspects, and/or the like), as described in more detail herein. In thiscase, based on received RTP data (e.g., RTP H.264 payload data),communication device 320 may assign portions of the received data todifferent code blocks and/or transport blocks, map the different codeblocks and/or transport blocks to different MIMO layers, and provide aset of data radio bearers (DRBs) based at least in part on the mapping.In this case, BS 110 may provide the video aware DRBs and RTCP outputdata over the Uu interface to UE 120.

UE 120 may receive the video aware DRBs and the RTCP output data via theUu interface. UE 120 may reconstruct the underlying RTP data (e.g., theRTP H.264 payload data) and process the underlying RTP data using avideo decoder (e.g., an RTP H.264 decoder) to obtain a decoded videostream.

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 3.

FIGS. 4A and 4B are diagrams illustrating examples 400/400′ of dataprocessing by a communication device to enable a BS to provide streamingvideo to a UE, in accordance with various aspects of the presentdisclosure.

As shown in FIG. 4A, a communication device (e.g., BS 110, communicationdevice 320) may decompose streaming content (e.g., streaming video) intoa plurality of portions associated with different characteristics toenable providing video aware DRBs. For example, the communication devicemay classify portions of the streaming content into an intra-codepicture (I-frame) category (e.g., a frame which may include an entireimage that is coded without reference to any other frame, but which mayinclude references to portions of the frame itself), a predicted picture(P-frame) category (e.g., a frame which may include image data andmotion vector displacements, and may reference previous frames in adecoding order), or a bidirectional predicted picture (B-frame) category(e.g., a frame which may include image data and/or motion vectordisplacements and may be decodable based at least in part on priordecoding of a subsequent frame that is to be displaced). These aresimply examples of categories that may be used. In practice, thecommunication device may classify the streaming content according to oneor more other types of heuristics. The communication device may assigndifferent portions of the streaming content to different DRBs forprocessing (e.g., for transport block cyclic redundancy check (CRC)attachment, code block segmentation, channel coding, rate matching, codeblock concatenation, and/or the like, as described in more detailherein).

In some aspects, the communication device may map transport blocks toMIMO layers based at least in part on a classification of the streamingcontent. For example, based at least in part on classifying a firstportion of the streaming content as having a relatively large effect ona quality of experience (QoE) (e.g., an absence of the first portion ofthe streaming content reduces a usability of the streaming content morethan an absence of other portions, such as by preventing a playbackdevice from playing any of the streaming content, which may affect QoEmore than, for example, a second portion of the streaming content thatis associated with maintaining exact synchronization between a video andaudio of the streaming content, without which playback may stillcontinue with, for example, poor synchronization), the communicationdevice may map a DRB including transport blocks of the first portion ofthe streaming content to MIMO layers with higher signal to noise ratio(SNR) values (e.g., providing a greater level of reliability relative toother MIMO layers). In contrast, the communication device may map a DRBincluding a second portion of the streaming content that has arelatively low effect on QoE to a MIMO layer with a lower SNR value(e.g., providing a lower level of reliability relative to other MIMOlayers). In this way, the communication device provides video awareprocessing of DRBs to enable greater quality of service (QoS) for DRBswith higher levels of effect on QoE, thereby providing greater QoE at aUE 120 that is to receive streaming content.

As further shown in FIG. 4A, based at least in part on processing theplurality of DRBs, the communication device may multiplex the pluralityof DRBs, modulate a multiplexed stream, perform resource mapping, andperform orthogonal frequency division (OFDM) symbol generation to enabletransmission of the plurality of DRBs with differential protection.

Similarly, as shown in FIG. 4B, the communication device may assigndifferent classifications of the streaming content to different codeblocks. For example, the communication device may assign I-frames to afirst code block, P-frames to a second code block, B-frames to a thirdcode block, and/or the like. Additionally, or alternatively, thecommunication device may classify portions of the streaming contentbased at least in part on other contemplated heuristics and assigndifferent classifications to different code blocks of a physical layertransport block. In this case, the communication device may map thedifferent code blocks to different MIMO layers based at least in part onan effect of content assigned to each code block on QoE of the streamingcontent and based at least in part on SNRs of the different MIMO layers.For example, the communication device may map a code block with high-QoEeffect portions of the streaming content to a high SNR MIMO layer and acode block with low-QoE effect portions of the streaming content to alow SNR MIMO layer. In this way, the communication device enablesvideo-aware processing to provide improved QoS to high-QoE code blocks,thereby providing higher QoE at a receiver device, such as UE 120.

As indicated above, FIGS. 4A and 4B is provided as examples. Otherexamples may differ from what is described with respect to FIGS. 4A and4B.

FIGS. 5A and 5B are diagrams illustrating examples 500/500′ of blockproduction by a communication device to enable a BS to provide streamingvideo to a UE, in accordance with various aspects of the presentdisclosure.

As shown in FIG. 5A, a medium access control (MAC) entity of acommunication device may generate a transport block (e.g., based atleast in part on service data adaptation protocol (SDAP) blockgeneration, packet data convergence protocol (PDCP) block generation,and radio link control (RLC) block generation). For example, the MACentity may concatenate two RLC protocol data units (PDUs) from a firstradio bearer (RB_(x)) and one RLC PDU from a second radio bearer(RB_(y)). After concatenation, the communication device may add cyclicredundancy check (CRC) bits and divide a transport block into aplurality of code blocks. In this case, code block 2, for example,includes data of the first radio bearer and data of the second radiobearer. As a result, based at least in part on data from a plurality ofDRBs being multiplexed into a common code block, the MAC entity providesthe same QoS (e.g., the QoS of the common code block) for each radiobearer.

In contrast, as shown in FIG. 5B, a communication device (e.g., BS 110,communication device 320, and/or the like) may include a MAC entity thatmay determine a code block size. In this case, based at least in part ondetermining the code block size, the MAC entity of the communicationdevice may allocate RLC PDUs to code block size units, such thatdifferent code blocks may be mapped to obtain different QoS, asdescribed above. For example, as shown, the first code block includesonly data from the first radio bearer and the second code block includesonly data from the second radio bearer. In this case, the communicationdevice may include padding bits to enable data of a radio bearer to fillan entire code block. In this way, based at least in part on ensuringthat each radio bearer is in a separate code block from each other radiobearer, the communication device enables QoE based video-awareprocessing without changing a layer 1 (L1) block production procedure.

As indicated above, FIGS. 5A and 5B is provided as an example. Otherexamples may differ from what is described with respect to FIGS. 5A and5B.

Forexample, the communication device (e.g., using controller/processor 240,transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234,and/or the like) may classify a set of packets of streaming videocontent based at least in part on one or more video characteristics, asdescribed above.
